Slide 2 - Greenhouse Effect The process of the atmosphere trapping heat from the sun. Without the atmosphere, heat would float off into outer space. Earth would be about 30°F each day without an atmosphere.
Slide 3 - Other Planets Any planet with an atmosphere, experiences the greenhouse effect.
Slide 4 - Earth’s Atmosphere 78% Nitrogen 20% Oxygen 2% Other (CO2 for example)
Slide 5 - Venus’s Atmosphere 96% CO2 3% Nitrogen 1% Other
Slide 6 - Greenhouse Gases The only gases in the atmosphere that have the ability to trap heat from the sun. Both natural and unnatural (human made) gases!
Slide 18 - Global Warming Boost in the greenhouse effect due to more greenhouse gases in atmosphere from human activities leading to warmer global temperatures.
Slide 19 - Global Warming Impacts Increase evaporation Ice at poles to melt
Slide 20 - Sea-Level Changes - Flooding Approx. 50% of the world’s population lives near coastlines, which may be under water in the future!
Slide 21 - What can you do? Turning off lights when not in use. Turning down heat in winter. Reduce air conditioner use in summer Recycling! Less energy is used to recycle than make from scratch. Use public transportation or drive fuel efficient cars.
Slide 22 - Venus Since it has a lot of CO2, it has a stronger greenhouse effect than Earth. The plant is about 860 Degrees Fahrenheit.
